‘Black Lives Matter’ mural painted outside Brooklyn Borough Hall

A massive “Black Lives Matter” mural was painted on a street outside of Brooklyn’s Borough Hall Friday as part of a city effort to have the message emblazoned on Big Apple roadways across the five boroughs.

The mural was painted in large yellow letters along Joralemon Street between Court Street and Boerum Place in Brooklyn Heights. The street has also been co-named “Black Lives Matter Boulevard.”

Mayor Bill de Blasio stopped by the mural and helped finish off the paint job in the afternoon.

Activists chanted “defund the NYPD” as Hizzoner used a paint roller to fill in the lettering with yellow.

The painting of the mural comes amid weeks of ongoing, nationwide protests against racial injustices and police brutality in the wake of the May 25 cop killing of George Floyd in Minneapolis.

Earlier this month, de Blasio announced that the city will have roadways painted and streets renamed in each borough to honor the Black Lives Matter movement.

A series of murals similar to the one painted on Joralemon Street will be painted throughout the five boroughs in the coming weeks.

One was recently painted in Brooklyn’s Bedford-Stuyvesant with the roadway becoming a pedestrian-only plaza for the summer.
